Hi all!
I'm new to netwok programming.
I wrote a server code to handle multiple clients on the same port and the
corresponding client code.
I listen and accepts client connects upto a number and stop listening.
When I send message from server to clients I could send only one message
to one client and for the remaining messages receivers are just taking
null values and nothing is being printed..
I tried debug but of no use..
Is it that you can only send one msg to one client.
Can some1 help me to sort this out

I'm probably not the person to answer the final question, but....... the person that can will need more info. Be as specific as possible. I'm guessing that somebody with more experience with this can help, but will need to know what protocol you are using at the very minimum. The more details the better.

Definitely. As a minimum we'd need to know what programming language you're using, and ideally see the code. Some questions: is your sever sending nulls, or are the clients just printing nulls because nothing is being received? How did you try debugging your app, and are you certain your server is even trying to send more messages? There is definitely no "one message per client" limitation.

Also, I suspect this should be in the programming forum, not newbie.
